Unusual Moves -- Ignite The Flames!

Is this title appropriate? Read and discuss in the comments section.

Yes, today, I will be bragging about another one of my brilliant games. The "unusual move" was an otherwise unprincipled move at an unexpected time. But it was the best move in the position and happened to work out. Note that this game was played on a different chess website I will not disclose the name of, however, the main point of the post is the chess moves, NOT the server it was played on.  Take a look at the position below:

I hope you learned something from this. Even though the ending was more "spectacular" (will be shown soon), I thought my 23rd move really set the tone for the rest of the game. I will also provide the PGN for the whole game for you guys to fiddle around with and critique my play with.  Bonus puzzle: Nine move later, how did I finish my opponent off?

Nice finish, don't you agree?  I hope you enjoyed this! Again, this game was played on a competitor website, though my only intention was to display the moves played. If you discover where this game was being played, please don't post publicly. Also, the time control was 15 minutes per side with 15 second increment. The rating of mine shown is provisional.
